I definitely don't think the romantic theme has been done enough. It's the opposite, really, it barely gets worked with. Romantic Garden definitely didn't complete the theme. That's a whimsical pack with mainly baroque objects and the Lost Garden of Healing with the wishing well. Other than jumping in the fountain, it isn't that romantic.
There has not been a larger pack centered on romance. A few romantic elements get patched in every now and then but previous versions had a lot more. There is definitely room to develop further.
I do want a country pack with horses and other animals as either a GP or an EP. The knitting pack would go well with that.
I might be open to a haunted GP if it includes the psychic/fortune teller as well.
More vacations in GPs are very welcomed by me, I'd definitely be interested in those. There really should be a deep snow world, an Italian world or other ideas like that. It's a little ridiculous that we don't have proper beach vacationing but at the same time, there would be an understandable outcry if they try to sell that separately given that it should have been in IL.
Actually, if they were to let the community vote on a new vacation world, I'd like that.
